Description

A kind of luwa evaporator processing oil waste liquid
Technical field
The utility model belongs to technical field of sewage, relates to a kind of luwa evaporator processing oil waste liquid.
Background technology
Luwa evaporator is widely used in the processes such as concentrated, the distillation of various solution.This device is mainly used in the process of petroleum wastewater liquid.Its cardinal principle is as follows: the chuck of the steam heating luwa evaporator of High Temperature High Pressure, need petroleum wastewater liquid to be processed after the heating of preheating and common vaporizer, vaporizer inside is tangentially entered into by upper end of evaporator entrance under the effect of dehvery pump, radially tube wall surface is dispersed in through centrifugal separator, at gravity, under the triple role of rotary scraping and centrifugal force, inner tube wall is formed the film of turbulence-like, laminar film and arc wave current, in spiral decline process, great heat transfer coefficient makes liquid evaporation very fast, when solution is concentrated and is even separated into solid state, discharge from the bottom part of vaporizer, secondary steam is then discharged by top.Secondary steam, after gas-liquid separator, enters MVR vapour compressor temperature-pressure, as the steam of heating jacket.
Existing luwa evaporator complex structure, the invention provides structure simple, effective wiped film vaporization apparatus.
Utility model content
The purpose of this utility model is to provide a kind of sewage disposal luwa evaporator, solves the problem that existing luwa evaporator complex structure cost is high.
The technical scheme that the utility model adopts comprises motor, motor is arranged on above speed reduction unit, speed reduction unit is fixed on speed reducer base, motor connection rotating shaft one end, drive axis of rotation, rotating shaft is perpendicular to ground, the rotating shaft the other end is arranged on setting head, rotating shaft runs through speed reduction unit from top to bottom successively, speed reducer base, feed chamber, cylindrical shell, rotating shaft there is seal cartridge with feed chamber connecting portion cover, feed chamber is provided with opening for feed, feed chamber connector drum upper end, cylindrical shell outer cover has chuck, chuck has opening to connect external heat source, cylindrical shell lower end is fixed together by bolt and setting head, rotating shaft in cylindrical shell is provided with scraper component.
Further, described scraper component is divided into three groups from top to bottom, and each group comprises three scraping blades, and scraping blade is fixedly connected with rotating shaft, and cylinder inboard wall is pressed close at the edge of scraping blade, and three scraping blades are evenly distributed around rotating shaft.
The beneficial effects of the utility model are that structure is simple, heat transfer efficiency is high, cost is low.
Accompanying drawing explanation

In figure, 1. motor, 2. speed reduction unit, 3. speed reducer base, 4. rotating shaft, 5. setting head, 6. feed chamber, 7. cylindrical shell, 8. seal cartridge, 9. opening for feed, 10. chuck, 11. scraper components, 12. scraping blades.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model as shown in Figure 1, comprise motor 1, motor 1 is arranged on above speed reduction unit 2, speed reduction unit 2 is fixed on speed reducer base 3, motor 1 connection rotating shaft 4 one end, rotating shaft 4 is driven to rotate, rotating shaft 4 is perpendicular to ground, rotating shaft 4 the other end is arranged on setting 5, rotating shaft 4 runs through speed reduction unit 2 from top to bottom successively, speed reducer base 3, feed chamber 6, cylindrical shell 7, speed reduction unit 2 and motor 1 form the drive part of luwa evaporator, rotating shaft 4 there is seal cartridge 8 with feed chamber 6 connecting portion cover, prevent feed liquid from entering drive part, feed chamber 6 is provided with opening for feed 9, feed chamber 6 connector drum 7 upper end, cylindrical shell 7 outer cover has chuck 10, chuck 10 has opening to connect external heat source, cylindrical shell 7 lower end is fixed together by bolt and setting 5, rotating shaft 4 in cylindrical shell 7 is provided with scraper component 11, rotated the material on cylindrical shell 7 inwall by the scraper component 11 that rotarily drives of rotating shaft 4.
As shown in Figures 2 and 3, scraper component 11 is divided into three groups from top to bottom, and each group comprises three scraping blades 12, and scraping blade 12 is fixedly connected with rotating shaft 4, and cylindrical shell 7 inwall is pressed close at the edge of scraping blade 12, and three scraping blades 12 are evenly distributed around rotating shaft 4.
The utility model luwa evaporator is the falling film vacuum evaporation mode adopted.After device start, petroleum wastewater liquid enters in the cylindrical shell 7 in vaporizer from opening for feed 9, be evenly dispersed on cylindrical shell 7 inwall, then scraped by the scraping blade 12 of high speed rotating the film faling apart into turbulent flow, increase overall heat transfer coefficient, improve evaporation capacity, the chuck 10 of cylindrical shell 7 overcoat connects external heat source, heat cylindrical shell 7, turbulent flow film flows downward and absorbs the heat that in chuck 10, medium transmits, and petroleum wastewater liquid flash evapn is concentrated; The scraping blade 12 rotated scrapes off the solid matter on wall, and liquid waste residues is discharged by bottom; Scraper component 11 is upper, middle and lower three groups setting, and each group scraper component 11 comprises three and coaxially installs around the evenly distributed scraping blade 12 of rotating shaft 4.Blade laminating cylindrical shell 7 inwall of scraping blade 12, through checking, waste liquid can be scraped loose by three groups of scraper components 11, the design often organizing three scraping blades 12 more effectively, timely, and efficiency is higher.
